Synopsis

Documentation

structVec2 :: [Float] -> [Vec2]Source

Example: structVec2 [1,2,3,4] = [ Vec2 1 2 , Vec2 3 4 ].

destructVec2 :: [Vec2] -> [Float]Source

The opposite of structVec2.

sinCos :: Float -> Vec2Source

unit vector with given angle relative to the positive X axis (in the positive direction, that is, CCW). A more precise name would be cosSin, but that sounds bad :)

sinCosRadiusSource

Arguments

:: Float

angle (in radians)

-> Float

radius

-> Vec2 

angle2 :: Vec2 -> FloatSource

The angle relative to the positive X axis

rotMatrix2 :: Float -> Mat2Source

Rotation matrix by a given angle (in radians), counterclockwise.

rotateCCW :: Vec2 -> Vec2Source

Rotates counterclockwise by 90 degrees.

rotateCW :: Vec2 -> Vec2Source

Rotates clockwise by 90 degrees.
